Interpreting the height/weight chart

This chart is only suitable for people aged 18 and over.

Underweight

If you're in the underweight range, there are a number of possible reasons for this. Your GP can help you find out more, and give you help and advice. Learn more by reading about nutrition for underweight adults.

Healthy weight

If you're in the healthy weight range, you're a healthy weight for your height.

It's still important to eat a balanced diet and include physical activity in your daily life to stay in good health. Adults should be active for at least 150 minutes every week.

Is this chart suitable for all adults?

This chart is suitable for most people aged 18 and over. However, it may not be suitable if you have a very muscular build.

This is because having lots of muscle may put you in the overweight or obese categories, even if you have little body fat. For example, professional rugby players can fall into the "obese" category despite having very little body fat. But this will not apply to most people.

In addition to BMI, your waist circumference can provide information about your health. You can learn more in What's your BMI?
